The 7.5 cm Geb. G. 36, used in the Tunisian campaign, is of comparatively recent manufacture. It can be broken down into six loads, each load having a maximum weight of 300 pounds. This enables the weapon to be used in mountainous country, as it can be easily transported by pack animal or in an airplane.
The tube is of monobloc construction, fitted with a perforated, six-baffled muzzle brake (some models of the gun are fitted with a perforated Solothurn type). The rear end of the piece is rectangular in shape, and dovetailed to fit into prepared recesses of the breech ring. A horizontal sliding type breech mechanism and continuous pull type firing mechanism are used in this gun. The recoil mechanism is hydropneumatic, but contrary to the usual design, both buffer and recuperator are positioned below the barrel.
The carriage is constructed of riveted and welded steel, with trunnion bearings to the rear. To preserve the proper balance, a spring equilibrator is located in the carriage immediately under the cradle. As is usual with most mountain guns, there is no shield. The carriage is mounted on steel disk wheels with solid rubber tires, and supported in firing position by riveted steel split trails with spade attachments.
The sight is graduated in mils from 0 to 1,250 (0° to 70° approx.) and also in meters from 0 to 1,000 (0 yds. to 1,094 yds.) for use with the hollow charge shell, 7.5 cm Gr. 38.
Both hollow-charge and high-explosive ammunition is used.

The 10.5 cm Geb. H. 40, introduced into the German Army in 1942, is the companion piece to the 7.5 cm Geb. G. 36 described on page 118. Its design is basically the same as that of the 10.5 cm le. F. H. 18 (M). The weapon can be split into nine loads for transport.
The barrel, of monobloc construction, is fitted with a double baffle muzzle brake with wide side flanges; the breech mechanism is of the horizontal sliding block type. A hydraulic buffer is built into the cradle on which the barrel slides in recoil, and a hydro-pneumatic recuperator is mounted above the barrel.
The split trail carriage has trails of riveted box construction which are fitted with large detachable spades. It is mounted on wheels of cast light alloy with detachable rims and solid rubber tires. The wheels are mounted on stub axles fitted to the trail legs and remain parallel to the legs when they are opened. Internal expanding brakes, adjusted by a handwheel from the front, are fitted to both wheels. The traversing and elevating handwheels are located on the left and right sides of the carriage respectively.
There are two range drum scales: one in mils ranging from 0 to 1,250; the other in meters ranging from 0 to 1,500 for hollow charge ammunition and from 1,500 to 9,675 for high explosive shells, both with charge 6 in the lower register.
